- Вмешательство
- Bivalirudin anticoagulation for ECMO
- Компаратор
- Heparin anticoagulation for ECMO
- Первичная конечная точка
- Hospital mortality, ECMO duration, major bleeding, thrombosis, circuit interventions
- Основной результат
- In adults, bivalirudin associated with lower hospital mortality (OR 0.65, 95% CI 0.44-0.95, p=0.03) and lower thrombosis (OR 0.55, 95% CI 0.37-0.83, p=0.004); no significant differences in major bleeding, ECMO duration, or circuit interventions

Ключевые выводы
- 35% relative reduction in hospital mortality with bivalirudin in adults
- 45% relative reduction in thrombotic events
- No difference in bleeding, ECMO duration, or circuit interventions
- Authors transparent about low evidence quality
- Complements parallel meta-analyses from Hasegawa, Huang, Wieruszewski
Ограничения
- All 10 included studies retrospective observational
- Significant heterogeneity could not be eliminated
- Authors explicitly note low overall evidence level
- Lack of standardization in anticoagulation targets
- Not applicable to whole-leech hirudotherapy
Клиническое значение
Li 2021 provides early systematic review evidence supporting bivalirudin survival and thrombosis benefits in adult ECMO, consistent with parallel syntheses. For ASH, this work demonstrates how aggregated retrospective observational evidence builds the case for the synthetic thrombin inhibitor pharmaceutical pathway, structurally separate from the K040187 device-leech US clinical practice. The author transparency about evidence quality models good methodological practice.
